Invar yog hlau-nickel austenitic alloy ntawm qis tshaj thermal expansivity. Nws muaj zog, tawv, ductile thiab muaj qhov muaj txiaj ntsig zoo ntawm kev tiv thaiv corrosion, nws yog sib nqus ntawm qhov kub thiab txias hauv qab nws Curie point thiab tsis sib nqus ntawm qhov kub siab tshaj. Invar yog li ntawd ib txwm sib nqus nyob rau hauv qhov kub thiab txias uas nws nthuav tawm cov yam ntxwv qis qis. Invar yog tus qauv alloy rau qis expansivity mus txog 400oF. Rau kev siv ntawm qhov kub thiab txias, cov nickel alloys siab dua raug pom zoo.

Kev siv
Nws yog dav siv hauv pwm rau cov khoom siv dav hlau sib xyaw, pwm rau cov khoom sib xyaw nkoj, cov phaj condenser, cov kab noj hniav resonant rau radars, kev ntsuas qhov tseeb, cov pob qij txha tshwj xeeb thiab cov ntxhua khaub ncaws,
thermostatic bimetals, laser ntu daim ntaub ntawv, moos pendulums, ntsuas lub log, saib qhov chaw, cuab yeej.
Machineability
Vim nws cov ductility siab, cov chips tsim thaum lub sij hawm machining zoo li yuav stringy thiab tawv, yog li imposing ceev ceev ntawm cov cuab yeej txiav. Feem ntau, qeeb qeeb thiab lub teeb txau yuav tsum tau siv kom tsis txhob muaj cua sov ntau dhau thiab txo qhov muaj peev xwm ntawm cov cua sov tsim los cuam tshuam rau cov yam ntxwv nthuav dav. Kev siv cov roj soluble txiav compound yog pom zoo rau txhua qhov kev ua haujlwm machining.
Ua haujlwm tau
Forging:Lub hauv paus tseem ceeb ceev faj kom saib xyuas hauv forging yog kom sov sai sai thiab tsis txhob soaking hauv qhov cub. Kev ntub dej ntev ntev tuaj yeem ua rau qhov chaw kuaj xyuas vim qhov nqus ntawm sulfur los ntawm qhov cub cua thiab / lossis oxide nkag.
Blanking thiab forming:Alloy 36 nthuav tawm tsis muaj teeb meem txawv txawv hauv kev blanking thiab sib sau. Rau kev ua kom huv si zoo tshaj plaws, Rockwell hardness ntawm B90 yog qhia. Qhov hardness no yuav cia me ntsis dabtsi yog khoov thiab sib sau ua haujlwm. Qhov twg kev ua haujlwm sib sib zog nqus tau koom nrog kev ua tiav cov hlua khi ntawm Rockwell harness txog B75 feem ntau yog qhov xav tau.
Sib tsoo:Lub log silicon carbide yog qhov xav tau, zoo dua yog lub log mos uas yuav hnav tsis muaj kev thauj khoom.
Vuam:Alloy 36 tuaj yeem welded los ntawm cov txheej txheem pa. Ceev faj yuav tsum tau ua kom tsis txhob overheat cov hlau molten. Qhov no yuav tsis txhob spattering ntawm molten hlau thiab pits nyob rau hauv welded cheeb tsam. Thaum welding nrog pas nrig, nws yog ib qho tseem ceeb uas tus pas nrig yuav tsum yog tib yam muaj pes tsawg leeg yog tias cov khoom zoo sib xws hauv cov vuam xav tau.Cov pas nrig yuav tsum tau coated hnyav. Nyob rau hauv oxyacetylene vuam, cov nplaim yog khaws cia me ntsis ntawm qhov txo qis.
Brazing:Nyiaj thiab zinc-dawb alloys tau siv rau brazing Invar 36. Cov hlau no yuav tsum tau annealed ua ntej brazing. Cov pob qij txha yuav tsum tau tsim kom tsis txhob tso cov khoom hauv qhov nro thaum brazing. Yog tias cov nyiaj soldering ua tiav manually, cov khoom yuav tsum tau preheated rau 800 oF thiab maj mam txias.
Plating:Alloy 36 tuaj yeem yog chromium, cadmium thiab npib tsib xee plated lossis zinc coated los ntawm cov txheej txheem ib txwm siv rau ferrous alloys.
Pickling:Pickling yog qhov ua tau zoo tshaj plaws hauv cov tshuaj hydrochloric acid. Ib qho 25% kev daws teeb meem ntawm 160 oF yog qhov tshwj xeeb zoo.
Distortion:Invar muaj cov thermal conductivity tsis zoo, qis coefficient ntawm kev nthuav dav ntawm qhov kub thiab txias hauv qab 300 oC,
ib txwm coefficient ntawm expansion ntawm qhov kub thiab txias, thiab elastic modulus 79% ntawm cov hlau. Cov xwm txheej no txhawb kev nyuaj siab thiab kev sib txawv. Ua tib zoo ua tib zoo saib nqe lus ntawm kev daws kev ntxhov siab. Peb xav kom cua txias sai sai es tsis txhob tso dej thaum twg los tau.
